Catto 2-blade or 3-blade prop?
Decisions decisions... Hoping some of you can weigh in and help me decide. I'm currently flying with a wood 2-bladed sensenich and reasonably happy with the performance. But, faster is better and it rains a lot here in Oregon so I have some concern over how the wood prop will hold up over time.
3-blade catto:
+ more ground clearance
+ looks better
+ smoother (subjective)
- more expensive
- harder to remove cowling
2-blade catto:
+ faster?
+ lighter
+ cheaper
- less ground clearance
- more vibration?
Or is the 2-blade versus 3-blade question one of those never ending debates?

I have (2) three blades and (1) two blade I fly with. Three blade IS smoother hands down. Two blade will climb better hands down. If you do the cut out mod/trim to the cowl as in the past RVAtor, the cowl on/off issue goes away for the three blade. And yes, the three blade looks awesome on the plane!
Ground clearance with either is not an issue. And as to cost... well in AMU's they're both cheap.

Got a link for that? I'm not aware of that mod and find getting the lower cowl on/off to be a PITA.
Thanks,

4th issue 2007 page 15, written by Scott McDaniels, head of Van's Prototype Shop...
I believe there's another example relating to this issue maybe it was a 2005 issue, I'll dig around a little more.

another request for copy of the mod
Last oil change was the first with the 3 blade catto installed, needed two of us to install the lower cowl. Very interested in a mod that will make it easier.

Same here. Even a .pdf by email would be great.
